With a properly setup sidecar, it's my experience, that they are very easy to maneuver. Depending on the bike and setup, they can be quite easy to steer. Don't have to worry about bad knees, ankles, etc. holding up a bike at stoplights, turns, etc. Can't drop one while at a standstill. Of course, there are limitations. I suppose if one has arthritis, carpel tunnel, etc., it could be difficult to operate a sidecar. But, they are sidecars made for people in wheelchairs, amputees, etc.

Plus, they look cool, and chicks dig 'em. Put a cute dog in the car and you will have to beat 'em off with your cane...
